A good writeup on the tech - https://spectrum.ieee.org/laser-cooling-chips
"The reemission is higher energy because it combines the energy from the incoming photons with phonons, vibrations in the crystal lattice of a material. This phenomenon is called anti-Stokes cooling, and it was first demonstrated in a solid back in 1995 when a team of scientists cooled an ytterbium-doped fluoride glass sample with laser light."

On a much larger scale, this could answer some of the challenges of cooling data centers in space. But it also could solve challenges terrestrially and potentially avoid some of the need for evaporative cooling (if you can direct the emitted light somewhere else, or recapture or).
